PHP - Get String Before Line Break

I'm trying to use SESSIONS, the start of my page looks like this:


<?php session_start();



and the start of the source code looks like this:


<br /> 
<b>Warning</b>:  session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cookie - headers already sent by 


The <?php tag is on line 1, yet as you can see Notepad++ seems to add a <br /> before it, which results in the sessions not working.

How can I fix this?

I'm trying to figure out how I can break a string down if the strings length is longer then lets say 140 characters including white space. At first I was figuring maybe maybe I could do something with explode or implode after I get a get my strings length but the string in question has no static values to them that would let me break it apart or put it back together. Now In most cases I would use substr() to return my 140 characters, however I need to take 140+ and make an array of the extra so I can run a for each on it.

I am using this for an SMS app I am helping develop. I know I can limit my the output to only 140, just based on the notion that a single SMS is capped at 140-160 on most carriers. Unfortunately for me thats not the case so I need to break this apart and I am stumped, anyone got any ideas?

I am extracting data from one of the sites.I would join these sentences separated by , (comma). The solution that comes to my head is by inserting the text in the file and then using file functions.However, i  was wondering if i can use str_replace here . Can anyone please point me in the right direction.

Code: [Select]
      Hospital 30-Day Death (Mortality) Rates from Heart Attack: 15.2% (No different than U.S. National Rate)
   
      Hospital 30-Day Readmission Rates from Heart Attack: % (Number of Cases Too Small*)
   
      Hospital 30-Day Death (Mortality) Rates from Heart Failu 10.5% (No different than U.S. National Rate)
   
      Hospital 30-Day Readmission Rates from Heart Failu 29.9% (Worse than U.S. National Rate)
   
      Hospital 30-Day Death (Mortality) Rates from Pneumonia: 9.8% (No different than U.S. National Rate)
   
      Hospital 30-Day Readmission Rates from Pneumonia: 20.6% (No different than U.S. National Rate)

hi,

i am using a database to populate a webpage with text. How do I make a function to add line breaks to the text?

an example page I want to use it on it
http://www.stayneartheairport.com/bandb.php?id=11084507&airport=manchester

You can see the two text areas of description and facilities have no paragraphs or other formatting.

I want the code to scan the text - and if there is say <br> - it will remove it an replace it with a line break.

so i have this string that i want to search on the database

My database has 3 parts city, state, country

and i have a string that is say "new york city, ny, united states"

and i want to be able to be able to look into the database but search those three sections so for example

"New York City" i would like to search under city
"NY" i want it to search under state
and "United States" i want to search under country

so basically how can i split the string  into those three sections??

hope someone can help me with this

how do I make this form here have a limit on the value's name, then it moves to the next line?

Code: [Select]
<form action=\"reply.php?com_id=$com_id\" method=\"post\">
<font color='brown'><u><input type=\"submit\" name ='submit' class=\"link\" value='$title'></u></font>
</form>

The table in the script has a set max-width. How can now a too long continuous text string as in "blaaaaaaaa", which also does not contain a space or dash, be broken, so the table does not become stretched to far?

Which function is used for this?

I am having problems with these slashes. They keep showing up when I echo data....
The code is to update a field in a mysql database table.

Here is my code:
Code: [Select]
$query = mysql_query("SELECT * FROM `bus` WHERE username='$username'");
$row = mysql_fetch_array($query);
$bio = $row['about'];
$bio = str_replace("<br />","\r\n",$bio);



if(isset($_POST['submit'])){
if(empty($errors)){
if($password == $pass){

$about1 = mysql_real_escape_string($_POST["about"]);
$about1 = str_replace("\r\n","<br />",$about1);

mysql_query("UPDATE bus SET about='$about1' WHERE username='$username'");

}else{$errors[] = 'Incorrect Password';}
}
}

When I run this and put:
About: 
I'm very tired today
It's been very hard

I get the about1 string as: I\\\'m very tired today\r\nIt\\\'s been very hard

Why???

This is probably a simple one. I just couldn't find a tutorial to the specific thing I'm trying.

I have a string that looks like: "(abbreviated name with.) second abbrev. name."

I'm trying to find a way to break this apart so I can have:

$var1 = "abbreviated name with."
$var2 = "second abbrev. name."

I've looked at substr and a couple others and I'm not sure quite how to do this, because the ')' could be in a differing location.

Hi to everyone.
So, I have a little php code that reads line by line from a txt file, specifically i have 1 IP address for each line, and compares it with the current user's IP. It's like a little blacklist code. But it doesn't work. Can anyone see what i am doing wrong?
Code: [Select]

$file = fopen("ipblacklist.txt", "r") or exit("Unable to open file!");
//Output a line of the file until the end is reached
$ipblacklist='';
$refile='';
while(!feof($file))
  {
  if (fgets($file)== $_SERVER['REMOTE_ADDR'])
       $ipblacklist='error';
     
  $refile=fgets($file);
  }
fclose($file);


Thank you in advance

Hey, all.  I'm new to php/mysql.

I'm getting the warning:
Quote

mysql_fetch_array() expects parameter 1 to be resource, string...line 39


with reference to the mysql_fetch_array function in the following code:

mysql_select_db("calculators", $con);

$query = "SELECT * FROM calculator WHERE Abbreviation = '" . $_GET['abbreviation'] . "'";

$result = mysql_query($query, $con);

while($row = mysql_fetch_array($result)) {
//some code...
  }



The code runs fine, but I'd like to know why I'm getting the warning.  I've looked at similar post on this forum and other forums and can't quite get a straight answer.

Thanks a bunch,

Davis

Hi.

I want a simple textbox, that when submited, will replace very every new line, with the <br> tag.

What will happen, when it submits, it will take the contents of a textbox, add the <br> tag where a new line is suposed to be, and save the string to a MySQL Database.

I think this is the easiest way of allowing a user to edit what appears on a website when logged in, but if there is a easier way, then please tell me.

What I am trying to do, is a login page, and once logged in, you enter new text into the textbox, click submit, and on the website homepage, the main text will change to what was submitted. But if there is a new line, I think the only way in HTML to make one is to put a <br> tag, so I want the PHP to but that tag wherever there is a new line.

Sorry if I am confusing, I am not that advanced at PHP, but I would be very happy if you could supply me with the correct code. Time is running out...

If you do not understand me, please tell me

Dear All

           Good Day, i am new to PHP (a beautiful server side scripting language). i want to send a mail with line by line message i tried with different types like by placing the things in table and using  <br /> but the thing is the tags are also visible in the message of the mail.

Here is my code:

$message1  = "Name       :".  $_REQUEST['name']."<br />";
$message1 .= "Surname    :".  $_REQUEST['surname']."<br />";
$message1 .= "Cellphone  :".  $_REQUEST['mobileno']."<br />";
$message1 .= "Telephone  :".  $_REQUEST['landno']."<br />";
$message1 .= "Fax        :".  $_REQUEST['fax']."<br />";
$message1 .= "Company    :".  $_REQUEST['company']."<br />";
$message1 .= "Email      :".  $_REQUEST['email']."<br />";
$message1 .= "Country    :".  $_REQUEST['country']."<br />";
$message1 .= "Enquity    :".  $_REQUEST['enquiry']."<br />";
$message1 .= "Date&Time  :".  $date."<br />";

For this code if try to print/echo it it is working fine it is displaying line by line, but using this variable ($message1) in the mail these <br /> are also visible.
Can any one guide me to resolve(to remove these tags from the message part) this issue.
Thanks in Advance. :confused:
